IMPROVED SILICIDE FORMATION BY IMPROVED SIGE FACETING

An integrated circuit includes a PMOS gate structure and a gate structure on adjacent field oxide. An epitaxy hard mask is formed over the gate structure on the field oxide so that the epitaxy hard mask overlaps the semiconductor material in PMOS source/drain region. SiGe semiconductor material is e...

description An integrated circuit includes a PMOS gate structure and a gate structure on adjacent field oxide. An epitaxy hard mask is formed over the gate structure on the field oxide so that the epitaxy hard mask overlaps the semiconductor material in PMOS source/drain region. SiGe semiconductor material is epitaxially formed in the source/drain regions, so that that a top edge of the SiGe semiconductor material at the field oxide does not extend more than one third of a depth of the SiGe in the source/drain region abutting the field oxide. Dielectric spacers on lateral surfaces of the gate structure on the field oxide extend onto the SiGe; at least one third of the SiGe is exposed. Metal silicide covers at least one third of a top surface of the SiGe. A contact has at least half of a bottom of the contact directly contacts the metal silicide on the SiGe.
